There will be a planned power outage for Malone Hall's G-29 Server Room, ''home to the CS central and CS faculty servers,'' on Friday, August 22, from 6am to 8am. (This is due to electrical work being done in that room.)

−
'''''CS IT SERVICES AVAILABLE/NOT AVAILABLE DURING THE POWER OUTAGE:'''''
+
: Both the MH 122 '''and''' G61 Masters and Ugrad Labs will be used for an ACM Programming Contest and will therefore be '''''closed''''' to those not participating in the contest.

The power outage runs from 6am to 8am, however we have to shut down all of our CS servers before-hand.
+
: Additionally, all of the labs' Linux computers (masters1 through masters16 and ugrad1 through ugrad24) will be unavailable during the time period referenced above.

Therefore, starting at 4:30am, here is a list of the CS-specific services that will or will not be available between 4:30am and until sometime after 8am when the power is restored and we can begin powering up our servers:

* During the lab closure times, compute servers, gradx.cs.jhu.edu, gradz.cs.jhu.edu, ugradx.cs.jhu.ed, and ugradz.cs.jhu.edu  '''''will continue to be available remotely''''', via SSH.
  
−
'''DHCP:''' available
+
* We have to take down the lab systems late that Friday afternoon.  At the end of the ACM contest that Saturday night, the coordinators of that contest will be turning our lab computer systems back on.  Most should boot normally.  But, if some do not, just trying using an alternate one in the lab.  We'll be back in the Monday afterwards and can check on any systems that didn't boot normally.  (And don't forget, as mentioned above our compute servers -- gradx, gradz, ugradx, ugradz -- will continue to be remotely available, even if the lab systems are not.)
  
−
'''Email:''' unavailable (a secondary server will accept mail sent to us, but no one will be able to check mail or send it through our CS servers.)
